DOOR-HANGER.

SPECIFICATION forming part'of Letters Patent No. 268,645, dated December 1882. Application filed August 30, 1882. (No model.)

To all whom it may concern Be it known that LEDWIN L. DUNHAM, a

citizen of the United States, residing at Quincy,

in the county of Branch and State of Michigan, have invented certain new and useful Improvements in Door-Hangers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains door-hangerwhich shall be more simple in conto make'and use the same, reference being had .to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. i

The present invention relates to that class of door and, gate hangers which consist essentially of a plate or bracket attached to the face ofthe door and carryingtop and bottom sheaves or wheels that run upon a track-rail secured to.

the wall of the building.

The object of the invention is'to provide a struction, efiective in operation, and capable of attachment to the door with greater ease and facility than other devices of an analogous character heretofore devised.

To these ends the invention consists in the construction and combination of parts which will be hereinafter fully described, and then set forth inthe claims.

In the drawings, Figure l is a perspective view exhibiting the wall of a building, a sliding door partly in section, and my improved hanger secured to the side of the door adjacent to the building. Fig. 2 is a vertical section through the ban ger, door, track, and wall of building. Fig. 3 is anedge view of the hanger with its top and bottom journals for the sheaves or wheels. Fig. 4. is a detail view of the upper journal and screw-threaded shank, designed to be secured to the hanger plate or body by casting the latter around the former. Fig. 5 is a detail view of the lower journal, designed to besecured to the hanger-platein the same manner as the upper journal. Fig. 6 is a perspective view of my hanger.

The letter A designates the attaching-plate or body of the hanger, which is made of cast metal and has at its upper end a stud or hollow boss, B, of a cylindrical or other form. This stud or boss projects from the inner face of the hanger-plate, and is designed for insertion into an opening made in the side of the [door adjacent to the wall of the building, as is clearly shown in Figs. 1 and 2. The boss B forms an integral part of the hanger-plate,being cast therewith. Through said boss and. the hanger-plate extends a wrought-iron bolt, which serves as an outer hearing or journal, (3, and an inner shank or stem, D. The end of thelatter is screw-threaded and passes through the door, being secured at the inner side thereof by a suitable nut,E. i The bolt forming the upper sheaNe-journal and screw-shank is secured in position by casting the metal of the hanger-plate and its stud around the same. In this manner the parts referred to are intimately united and a separation is effectually prevented. A second sheave-journal, F, and screwshank G, with not similar to the one already described with the exception of the-boss, is secured to the hanger-plate at or near the bottom thereof, by casting in the same manner as the upper journal. This bolt is also made of Wrought-iron and has a flange, f, which bears against the face of the hanger-plate. It will thus be seen that the stud or boss B and the screw-sha ks D and G fasten the hangerfirmly to the door without the use of additional fastening devices. The upper journal carries a sheave or roller, K, which has a plain or smooth periphery and runs upon the top of a rail or track, H. The latter is secured to the wall of a building in any suitable manner, and is generally faced with metal in order to prevent wear. .The sheave or roller turns upon the journal, and is held thereon by riveting or spreading the end of thejournal upon a washer,

I, interposed between said end and the face of the roller. The sheave or pulley J turns upon the lower journal and has a flange, j, on the edge adjoining the wall of the building. Said flange runs in a groove or ledge, m, on the lower face of the rail, and its object is to prevent the lateral movement or displacement of the door. The periphery of the upper sheave, K, is slightly beveled or conical, the greatest diameter of the sheave being placed adjoining the hanger-plate or at the outer edge of the rail. The objectof making the sheave slightly conical is to prevent the hanger from rubbing the track or rail, it being manifest that the sheave has a tendency to keep the door away from the rail. 7

Adoor-hangerconstructcd as abovedescribed struction a face-plate or bracket having two can be easily and cheaply manufactured, is strong and durable in use, and can be secured to a door with facility and dispatch.

I am awarethat a door-hanger has heretofore been devised which embodies in its coniournals for the reception of sheaves or wheels that run in contact with the top and bottom faces of a rail secured to the wall of a building.

I-am also aware of the existence of a doorhanger consisting of a sheave by which the door is suspended and a flanged stud forming the axisof said sheave attached to the door on the side thereof next to the wall of the building by being socketed in a'hole in the door, below the top, and held by a nut on its outer end; but

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the cast-metal hangerplate A, having the boss B and the wroughtrnetal upper sheave-journal, (J, and screwshankl) and wrought-metal lower sheave-journal, F, and screw-shank G, intimately secured to said hanger-plate, with the top and bottom sheaves, K J,,and rail H, as and for the purpose specified.

In testimony whereof I affix my signature in presence of two Witnesses.

EDWIN LORENZO DUNHAM.
